Description
Technical field
The present invention relates to packaging material for food application, particularly relate to a kind of double down solution food package film.
Background technology
In recent years, along with improving constantly of people's quality of life, the fast development of food industry, food pack can be again
While extending the shelf lives of food, keep the instrument of freshness of food, thus use the most extensively, more and more frequent.
Problem of environmental pollution has become the key factor hindering economic development at present, and along with the raising of people's environmental consciousness, " white is dirty
Dye " problem becomes the focus of social concerns, and plastic packing bag becomes one of polluter important in " white pollution ".
Develop row nontoxic, that environmental protection food pack solves the white pollution problems thereby resulted in beyond doubt
Effective method.There are at present some by natural macromolecular material, as cellulose, starch, sodium alginate, chitosan and
Protein etc. are for the research of food package film and application, and this is the biodegradable that make use of natural macromolecular material, reaches
Arrive degraded requirement.But the research utilizing light or organisms two ways to carry out the food package film degraded not yet occurs.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of double down solution food package film, give up at packaging film
Degradable by light or organisms can be carried out after abandoning, reach the purpose of environmental protection.
For achieving the above object, the technical scheme that the present invention takes is as follows:
A kind of double down solution food package film, described double down solution food package film is layer structure, and ecto-entad is followed successively by transparent
Protective layer (1), printing layer (2), printing element layer (3), degradable barrier layer (4) and biodegradable hot sealing layer (5), described
Protective clear layer (1) and printing element layer (3) in be added with photosensitizer, described degradable barrier layer (4) is by containing photosensitive
The monomer of group is made with olefin monomer copolymerization, and described biodegradable hot sealing layer (5) is by the aliphatic containing ester group structure
Polyester is made, by being hot bonding between described double down solution food package film adjacent layer.
Preferential, described protective clear layer (1) is polyolefin.
Preferential, described printing element layer (3) is two-way stretching polyamide or Biaxially oriented polypropylene.
Preferential, in described protective clear layer (1) and printing element layer (3), photosensitizer is benzophenone, ferrocene, firmly
Fat acid ferrum or alkylthio carbamic acid ferrum.
Preferential, the described monomer containing photosensitive group in degradable barrier layer (4) is ethylene methacrylic ketone, methyl
Propenone or vinyl alcohol cinnamate.
Preferential, the described monomer containing photosensitive group in degradable barrier layer (4) is vinyl alcohol cinnamate.
Preferential, the described olefin monomer in degradable barrier layer (4) is ethylene or propylene.
Preferential, the described aliphatic polyester containing ester group structure in biodegradable hot sealing layer (5) is polylactic acid, gathers
Caprolactone or polyesteramide.
Preferential, the thickness of described protective clear layer (1) be 20-40 micron, the thickness of printing element layer (3) be 20-
40 microns, the thickness of degradable barrier layer (4) be 20-40 micron, the thickness of biodegradable hot sealing layer (5) be that 20-40 is micro-
Rice.
Beneficial effects of the present invention is as follows:
1. the existence of protective clear layer (1), while not affecting the visual effect of printing layer pattern, it is possible to ensures printing layer figure
Case lasting.
The agent structure of the most degradable barrier layer (4) be ethylene-vinyl alcohol as main chain, there is the advantages such as good barrier property,
Carbonyl in main chain is as photosensitive group simultaneously, can carry out light degradation in external environment.
The agent structure of the most degradable barrier layer (4) is to introduce photosensitive group by copolymerized form, it is to avoid little molecule
The use of photosensitizer, on the one hand improves packaging film strength, also prevents protective clear layer (1) and printing element layer simultaneously
(3) in, photosensitizer is to the migration of inner side.
The most biodegradable hot sealing layer (5) is made up of the aliphatic polyester containing ester group structure, and the most such ester group is tied
Structure can carry out biodegradation under microbial environment, on the other hand utilizes this type of structure proximate natural polymer material synthesized
Material, it is also possible to overcome and become the shortcomings such as difficult, the film properties difference of processing technique during packaging film by pure natural Process Technology of Polymer.
By thermo-compression bonding between each layer of the most double down solution food package film, do not use binding agent, it is possible to reach food bag
The safety and health request of pack.
